To vzZZ whom it may concern:

Be it known that I, HARRY Fonnsi' Gnrsr,

a citizen of the United States, residing at Sumter, in the county of Sumter and State of South Carolina, have invented certain new and useful Improvements in Ignition Devices, of which the following is a specification, referencebeing had to the accompanying drawing.

a The invention relates to new and useful improvements in ignition devices for interactuated.

A further object of the invention is to provide a device of the above character wherein a spring is utilized for moving the ignition points toward each other and for holding the same in contact and wherein devices are provided for increasing the tension of the spring through the movement of the rotor or armature toward releasing position.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

in the drawings which show illustration one embodiment of tion;

Figure 1 is a side view of an ignition de vice embodying my invention;

Fig. 2 is a view partly in section and artly in side elevation, showing the trip ever, a portion. of the springs for-actuating the sameythe electrodes and the supporting bracket therefor, with the trip lever in normal idle position;

by way of t 1e invenliig. 3 is asimilar view but showing the connection of the springs to the trip lever and also showing the trip lever moved to the point of release; and

.lFig. 4; is a view similar to Fig. 3 but showing the trip lever released and thrown to to position for separating the ignition points.

The invention consists generally of an 1gn1t1on device having a fixedeleetrode and a movable electrode carrying ignition points. 7

The movable electrode is spring pressed so as to normally hold the ignition points in contact. Current is furnished to the igni tion" pointsby a generator of the oscillating type; that 1s, wherein the rotor or armature is actuated by means of a spring or springs .through'the aid of atrip leverand a pushrod which'operates upon the trip lever to store power in the springsand releases the same so that the rotor or armature may be moved through the stored power for providmg a maximum current for ignition n proper timing with the movements or the piston in the cylinder. The movable ectrode is operated for separating theh'gni t ron. timing with the movement ofthe points in rotor or armature. The, springqpressed means for moving the ignition points in engagement is so connected or associated with the trip lever for moving the rotor or armature, that the tension of the spring isincreased as the armature is moved toward releasing position, so that the ignition points will be firmly pressed into contact at this time.

Referring more in detail to the drawings,

T have shown my invention-as embodied in an ignition device which is supported bracket structure indicated .at 1. This bracket is attached to the cylinder wall by a,

which is indicated at 2.' Mounted in the bracket is a fixedel'ectrode 3 and a movable electrode 4. A movable electrode in the cylinder carries an arm 5 which supports an ignition point 6, which is adapted to 006perate with theignition point 7 on the fixed electrode. These parts are of the usual construction and have only been shown more or less diagrammatically in the drawings. Current is supplied to the ignition points from a generator G, which is mounted on the supporting bracket 1. The generator is'provided with a rotor or armature 8, on the outer end of which is a bifurcated arm 9. Pivotally supported by the bracket 1 is atrip lever 10, which is provided with oppositely extending arms 11 and 12. A spring 13 is connected to the arm 11 at its inner end and at its outer end to a pin 14 carried by the supporting bracket 1. A spring -15 is connected at 1ts inner end to the arm Hand are in normal idle position as shown in .L- .1, his L 13 and 15ers substsniislly in slmemenc. l l hen the trip is ver is moved to the position shown in Fig.

1 3. these springs are moved out of zilinement the ins; current {or i .the normal tension is sncl. power is stored in the springs, which is utilized when the trip lever is released to move the armature or rotor very rapidly, so as to produce an ellicien's current for ignition purposes although the sgaeed of the enrpq he may he very slow. so firip lever 10 is with on erm Ji'having a cam face c is adapted malre contact with a. can: see fi ion an arm 2;: fixed to the shank the movable electrode. These cam faces E22 and 23 are molly out of contact when the parts are iile as shown in Fig. 2. When the trip lever is relessed,'i;he momenbum of the trip lever carries the springs past 'slinement as shown in Fig. l, bringing the cam face 29. inino contact with the cam face 23, which moves the movable elecirode so as to sepsrse lhe ignition points to produce the spark. "Elie arm 24: is extended forwardly indicated at 25. A. spring; 26 is connected one end to the outer end oi the arm 25 and its other QIKliJO 1). lug 2? on T his spring 5 turns the movable electrode in. s clockwise direction and this forces the movable ignition point lsoward the fixed ignition point and holds said ignition points in contact when the pan-is are in normal idle position as shown in Fig. 2. The spring is so proporiioneci that the ignition points are lig tly held in contactst this time. When the trip lever is moved fol; storing power in the springs 13 and 15, thelug 27 is moved away from the outer end of the arm 25 and this increases the tension of the spring 26, so that the ignition points will be forced into contact v i al. increasing pressure until the trip lever 'i'esches the point of release. T his rension of will of course decrease as soon as lever moves hrough the action of the swings '13 and 15 for generath iision purposes. Not only or" the spring decrease until reached, but as the parts through momen um, more to the posii W i v r1011 shown in r 155. s, the tension of the spring will be decreased below the normal will the in soone no other.
